Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

It should be understood that the terms “comprising,” “including,” and “having” are inclusive and therefore specify the presence of stated features, numbers, operations, components, units, or their combination, but do not preclude the presence or addition of one or more other features, numbers, operations, components, units, or their combination. In particular, numerals are to be understood as examples for the sake of clarity, and are not to be construed as limiting the embodiments by the numbers set forth.

“Content” may be any type of data which may be input in an electronic device, generated by the electronic device, or output at the electronic device. For example, the content may be an image, vector image, video, animation, background, workspace, work object, audio, text, vibration, etc., or their combination. Terms such as, base content, input content, output content, reconstructed content, target content, fake content, real content are used herein to distinguish each content mentioned in each operation of methods according to an embodiment, and their meanings can be easily understood by those skilled in the art based on context. For example, the base content may refer to content which is a subject of edit, modification, compositing, etc. The base content may be a workspace of an application. For example, the base content may be a document which is a workspace of a document editing application, a slide which is a workspace of a presentation editing application, a spreadsheet which is a workspace of a spreadsheet editing application, a user creation mode in a game application, a drawing document of a drawing document of a drawing application. Meanwhile, terms referring to content may refer to content of the same type, for example, images, but is not limited thereto. The terms referring to content may refer to content of different types. For example, the base content may be a workspace, the input content may be an image, and the output content may be an animation of the image.

The user input may be related to one or more coordinates, but is not limited thereto. For example, the user input may be an audio input, voice input, text input, or a combination thereof. An input related to a coordinate may be a touch input, click input, gesture input, etc.

“Natural language input” refers to an input received at the electronic device in the form of language people use every day, and may be a voice input, text input, or a combination thereof.

FIG. 1 is a diagram for schematically explaining iterative generation of content according to an embodiment of the disclosure.

Referring to FIG. 1 , an electronic device 2000 may generate output content 112 based on a natural language input and a user input of a user. The output content 112 may be generated by compositing input content onto the base content 100. The base content 100, input content and output content may be images, but are not limited thereto. A specific method of generating the output content 112 may be explained later by referring to FIGS. 7A and 7B.

In an embodiment, the input content used in generation of the output content 112 may be determined based on the natural language input of the user. For example, referring to FIG. 1 , an image of a cat or perching cat may be determined as input content based on a natural language input saying “draw a cat perching on here.” The input content may be determined from a plurality of pieces of content stored in the electronic device 2000, or determined from images obtained by searching the Internet. A method of determining input content based on a natural language input will be explained by referring to FIG. 5 .

Referring to FIG. 1 , the output content 112 may be generated in a target area 102 of the base content 100. The output content 112 may be generating by compositing the input content onto the target area 102 of the base content 100 The target area 102 refers to an area of the base content 100 on which the input image is composited. The target area 102 may be an entire area or a partial area of the base content 100. The target area 102 of the base content 110 may include the generated output content after compositing. According to an embodiment, efficiency of a compositing process may be improved by compositing the input content into the target area 102 of the base content 100, because the number of pixels for compositing is decreased compared to when compositing the input content into an entire area of the base content 100.

The target area 102 may correspond to a bounding box including an object detected or localized in the base content 100, such as, a desk, chair, or bench. The base content 100 may include a plurality of areas, such as a plurality of bounding boxes respectively including an object. The target area 102 may be selected from among the plurality of bounding boxes by a user input. A size and shape of the target area 102 may be adjusted by a user input such as a drag input. The target area 102 may have a predetermined size and shape.

Referring to FIG. 1 , a caption for the generated output content 112 may be generated. The caption for the generated output content is text for the output content 112, and may be generated by using an image captioning model. The caption may be text for describing the output content 112. In an embodiment, similarity between text of the natural language input and the output content 112 may be calculated. The generated output content 112 may be displayed at the electronic device 2000 based on the similarity. In an embodiment, a process of generation of the output content 112 may be iterated when the similarity does not meet a certain condition. For example, the process of generation of the output content 112 may be iterated by compositing another input content into the target area 102 of the base content 100. For example, the process of generation of the output content 112 may be iterated by compositing the same input content into the target area 102 of the base content 100, which will be explained later by referring to FIGS. 7A and 7B.

According to an embodiment, the process of generation of the output content 112 may be iterated based on the similarity between the text of the natural language input and the caption for the output content 112, so that the generated output content 112 may conform to intention of the user.

Meanwhile, various operations explained in the disclosure such as interpretation of the natural language input the a user, generation of the output content 112, generation of the caption for the output content 112, calculation of the similarity between the text of the natural language input and the caption may be performed by an artificial intelligence (AI) model. The AI model may be referred to as a neural network model. The AI model may include a plurality of neural network layers. Each of the neural network layers may have a plurality of weight values and may perform various neural network computations via arithmetic operations on results of calculations in a previous layer and a plurality of weight values in the current layer. A plurality of weights in each of the neural network layers may be optimized by a result of training the AI model. For example, a plurality of weights may be updated to reduce or minimize a loss or cost value acquired by the AI model during a training process. An artificial neural network may include, for example, and without limitation, a deep neural network (DNN) and may include, for example, and without limitation, a convolutional neural network (CNN), a DNN, a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent DNN (BRDNN), deep Q-networks (DQN), or the like, but is not limited thereto.

The electronic device 200 may be implemented by more or fewer components than the components shown in FIG. 2 . In the disclosure, modules of the electronic device 200 are named to distinctively explain their operations which are performed by the modules in the electronic device 200. Thus, it should be understood that such operations are performed according to an embodiment and should not be interpreted as limiting a role or a function of the modules. For example, an operation which is described herein as being performed by a certain module of the electronic device 200 may be performed by another module or other modules of the electronic device 200, and an operation which is described herein as being performed by interaction between modules of the electronic device 200 or their interactive processing may be performed by one module of the electronic device 200. Furthermore, an operation which is described herein as being performed by the electronic device 200 may be performed at or with another device to provide substantially same functionality.

FIG. 3 illustrates a flowchart of a method according to an embodiment of the disclosure.

Referring to FIG. 3 , in operation S310, user intention information may be obtained based on a received natural language input. The user intention obtaining unit 210 of the electronic device 200 may obtain the user intention information based on the received natural language input.

The user intention information may indicate intention of a user interpreted from the natural language input (or its text) of the user by the electronic device 200. The user intention information may include action information regarding an action that can be performed at the electronic device 200. The action information may be inferred a verb in the text of the natural language input. For example, generation of content may be identified as the action information from a verb “draw” of the natural language input saying “draw a cat perching on here.” Words indicating the generation of content is not limited to “draw”, and may be various. The electronic device 200 may perform an action indicated by the action information. For example, the electronic device 200 may generate output content in response to identifying, from user intention information, action information indicating generation of content. In an embodiment, the user intention information may be obtained by using an AI model, which will be explained later by referring to FIG. 5 .

In operation S320, a target area may be set in a base image based on a user input. The target area setting unit 220 of the electronic device 200 may set the target area in the base content based on the user input. The target area may be an entire area or a partial area of the base content. Furthermore, the target area may be an area which can be adjusted in the base content by the user input. The target area may correspond to a bounding box recognized in the base content. In an embodiment, recognition of the bounding box may be performed by an AI model.

In an embodiment, the user input and the natural language input may be received at the electronic device together. For example, when a user touching a displayed base content in the electronic device 200 while speaking, a user input of the touching and a natural language input of the speaking may be simultaneously received at the electronic device.

In operation S330, input content may be determined. The input content determining unit 230 of the electronic device 200 may determine the input content. In an embodiment, the input content may be determined based on the user intention information obtained in operation S320. For example, when the user intention information includes content information, the input content may be determined based on the content information. The content information may be interred from a noun in the text of the natural language input. For example, a noun “cat” may be identified as the content information from the natural language input saying “draw a cat perching on here” In an embodiment, a name of an entity may be identified by using the named entity recognition (NER) as the content information. The electronic device 200 may determine an image of a cat as the input content in response to identifying “cat” as the content information from the text of the natural language input. In an embodiment, the content information may be inferred from an object of the text of the natural language input For example, an object “a cat perching” of a verb “draw” may be identified from the natural language input saying “draw a cat perching on here”, and the electronic device 200 may determine an image of a cat as the input content. The input content may be determined from a plurality of pieces of content (such as images) stored in the electronic device 200, or determined from the plurality of pieces of content obtained by searching Internet. The content information may indicate a subject to be input to an AI model to perform an action indicated by the action information.

In an embodiment, the input content may be determined by a user input. For example, content selected by a user at the electronic device 200 may be determined as the input content. A specific method of determining the input content may be explained later by referring to FIGS. 6A and 6B.

Meanwhile, the user intention information may be used to set a target area in the base content according to an embodiment. The user intention information may include area information. An expression indicating a place or location such as “here”, “there”, “everywhere”, “somewhere”, a preposition and postposition indicating a location, and any word connected to the preposition and postposition indicating a location may be identified from the text of the natural language input as the area information. In an embodiment, the target area may be set as an area indicated by the area information with respect to a location which may be selected in the base content by a user input. When a bounding box is selected in the base content by the user input, an area indicated by the area information may be set as the target area with respect to the selected bounding box. In an embodiment, the target area may be set in the base content based on the user intention information.

In an embodiment, the user intention information may include content attribute information. For example, when content information corresponding to “cat” is identified from the natural language input saying “draw a cat perching on here”, a word “perching” modifying the content information may be identified as the content attribute information indicating an attribute of content, which will be explained later by referring to FIGS. 8, 9, and 10 .

In operation S340, output content may be generated based on the input content, the target area, and the user intention information. The output content may be generated in relation with the base content. The output content generating unit 240 of the electronic device 200 may generate the output content based on the input content, the target area, and the user intention information. The output content refers to content generated by the natural language input of the user, and may include content which is output by the electronic device 200 and shown to the user, and may also include content which has been generated but not shown to the user. In an embodiment, the output content may be generated by using an AI model, which will be explained later by referring to FIGS. 7A and 7B.

In operation S350, a caption for the output content may be generated. The caption generating unit 250 of the electronic device 200 may generate the caption for the output content. In an embodiment, the caption for the output content may be generated by using an AI model. For example, the caption for the output content may be generated by using an image captioning model. For example, the caption for an animation of the output content may be generated by using a voice captioning model. Various imaging captioning models and video captioning models are already known by those skilled in the art, thus, redundant explanation is omitted.

In operation S360, similarity between text of the natural language input and the caption may be calculated. The similarity calculating unit 260 of the electronic device 200 may calculate the similarity between the text of the natural language input and the caption. The text of the natural language input may be determined in the process of obtaining the user intention information from the natural language input in operation S310.

In an embodiment, the similarity between the text of the natural language input and the caption may be calculated by using an AI model. The similarity may be vector similarity. The text of the natural language input and the caption may be encoded using semantic vector to generate corresponding vectors, and similarity between the vectors may be calculated.

In operation S370, whether the similarity satisfies a condition may be determined. In an embodiment, when the similarity exceeds a preset threshold, the condition may be satisfied. In an embodiment, when the similarity is within a preset range, the condition may be satisfied.

When the similarity satisfies the condition in operation S370, it may be determined that the generated output content conforms to intention of the user. When the similarity does not satisfy the condition in operation S370, it may be determined that the generated output content does not conform to the intention of the user.

In an embodiment, when the generated output content does not conform to the intention of the user, that is, when the similarity does not satisfy the condition, a process of generating the output content may be iterated in order to generate the output content conforming to the intention of the user. For example, operations S340, S350, S360, and S370 may be iterated.

In an embodiment, when the generated output content does not conform to the intention of the user, that is, when the similarity does not satisfy the condition, another input content different from the input content selected in operation S330 may be determined, and then operations S340, S350, S360, and S370 may be iterated with the newly determined other input content in order to generate the output content conforming to the intention of the user.

According to an embodiment, output content conforming to the intention of the user may be generated by comparing the natural language input of the user and the caption for the output content. Furthermore, the quality of the output content may be improved by iteration of generating the output content.

FIG. 4 is a diagram for explaining an example content generated according to an embodiment of the disclosure.

In an embodiment, the target area set in the base content is illustrated as a rectangle in FIG. 1 , but is not limited thereto, and may be a circle, oval, triangle, pentagon, polygon, or have any shape.

Referring to FIG. 4 , based on a natural language input saying “put Amy's face here” and a target area 412 a set by a user input, input content of “Amy's face” may be composited into a target area 412 a to generate output content, and then, base content 410 a, into which the generated output content is composited, including the composited output content may be provided to the user. The input content may be obtained by searching the Internet.

In an embodiment, the input content may be obtained from images stored in the electronic device or a cloud server by using an AI model. Images captured by the user may be processed in the electronic device or the cloud server by using a face detection AI model, and detected faces may be named directly by the user, or by using a browsing history of social network service (SNS) of the user. Accordingly, a face named as “Amy” may be determined from the detected faces as the input content.

In an embodiment, output content is generated by compositing the input content into the target area 412 a of the base content 410 a, and then a caption for the generated output content, for example, “Amy's face between friends” may be generated. The caption for the generated output content may be compared to the text of the natural language input, and whether to iterate generation of the output content may be determined based on the comparison.

In an embodiment, a bounding box including a face may be recognized from the base content 410 a by using an AI model, the target area 412 a may be set based on the recognized bounding box. When a natural language input saying “replace Bell's face with Amy” is received at the electronic device and Bell's face is detected in base content 410 a, the Bell's face may be set as a target area 412 a.

Referring to FIG. 4 , input content 402 b of “cat” or “jumping cat” may be composited into a target area based on a natural language input saying “put a jumping cat here” to generate output content. In an embodiment, the input content 402 b may be determined from base content 400 b by using an AI model. For example, when content information derived from the natural language input corresponds to an object detected in the base content 400 b, the detected object may be determined as the input content 402 b. In an embodiment, an attribute of the input content 402 b detected in the base content 400 b may be changed based on user intention information. The user intention information may include content attribute information, and the content attribute information may relate to pose. Furthermore, a pose animation corresponding to a pose indicated by the content attribute information may be obtained. The pose animation of the pose of the content attribute information may be obtained from a pose animation library. The pose animation library may be generated by detecting key points from bodies of animals or people using an AI model.

In an embodiment, the input content 402 b may be a pose animation obtained based on the user intention information. The output content may be generated based on an object in the target area and the pose animation by using an AI model. When the base content 400 b is a video, each frame of the base content 400 b may be modified based on the pose animation to generate the output content, and then the base content 410 b including the output content may be provided to a user. A size and shape of the target area may be adjusted according to the pose animation.

In an embodiment, the output content is generated by compositing the input content 402 b into the target area of the base content, and then a caption for the generated output content, for example, “a jumping Russian Blue cat” may be generated. The caption for the generated output content may be compared to a text of a received natural language input, and whether to iterate generation of the output content may be determined based on the comparison. An AI model such as a video captioning model may be used to generate the caption for the output content.

In an embodiment, a bounding box including an object may be recognized from the base content 400 b by using an AI model, the target area may be set based on the recognized bounding box. The input content 402 b may be determined from the bounding box or target area of the base content 400 b.

Referring to FIG. 4 , when a natural language input saying “draw the sun in black and white here” is received at the electronic device, input content of “sun” or “sun in the black and white” may be composited into a target area 412 c to generate output content, and then base content, into which the output content is composited, may be provided to a user.

In an embodiment, the output content may be generated as having the same form with the base content 410 c by using an AI model. For example, when the base content 410 c is an image of a cartoon type, the output content may be also generated as an image having the same cartoon type. The image of the cartoon type may be a vector image. Output content may be a vector image converted from an image. In an embodiment, the output content may be generated based on commands supported by a vector drawing program. The output content may be generated based on an application programming interface (API) of a program. A method of generating output content based on an API of a program will be explained later by referring to FIGS. 15 and 16 . According to an embodiment, output content may be generated in various platform, and not limited to image compositing.

In an embodiment, output content is generated by compositing the input content into the target area 412 c of the base content 410 a, and then a caption for the generated output content, for example, “black hole” may be generated. The caption for the generated output content may be compared to the text of the natural language input, and whether to iterate generation of the output content may be determined based on the comparison. When the similarity between the caption of the output content and the text of the natural language input of the user does not satisfy a certain condition, a process of generating output content may be iterated. Iterative generation of output content may continue until output content is generated to have a caption similar to the text of the natural language input “the sun in black and white.”

Referring to FIG. 4 , when a natural language input saying “make a door here” is received at the electronic device, input content of “door” may be composited into the target area 412 d to generate output content which matches with the base content 410 d, and then the base content 410 d including the generated output content may be provided to a user. In an embodiment, the output content may be generated in the same platform with the base content 410 d by using an AI model. That is, the output content may be generated as being limited to the platform to which the base content 410 d belongs. For example, when the platform of the base content 410 d is a certain game, the output content may be generated as a way supported by the game. The game may be a sandbox game or game creating tool. In an embodiment, the output content may be generated based on commands supported by the game. The output content may be generated based on an application programming interface (API) of a game. According to an embodiment, output content may be generated in various platform, and not limited to image compositing.

FIG. 5 is a diagram for explaining a method for obtaining user intention information according to an embodiment of the disclosure.

In an embodiment, user intention information may be obtained based on a natural language input of a user.

Referring to FIG. 5 , the user intention obtaining unit 210 of the electronic device may include an automatic speech recognition (ASR) model 212 and a natural language understanding (NLU) model 214.

Referring to FIG. 5 , when a voice input is received as a natural language input, a voice of the natural voice input may be converted into text through the ASR model 212, and then, the converted text may be processed by the NLU model 214 to obtain the user intention information. The voice input may be received by a microphone of the electronic device. The text converted through the ASR model 212 may be compared with a caption generated for a generated output later, and similarity between the text of the natural language input and the caption for the generated caption may be calculated as a result of the comparison.

In an embodiment, the user intention obtaining unit 210 may include a spoken language understanding (SLU) model, a voice input received through a microphone may be processed by the SLU model to obtain user intention information. In an embodiment, the natural language input may be transmitted from another device.

In an embodiment, when a text input is received as a natural language input, the NLU model 214 may process text of the text input to obtain user intention information. The text input may be received by an input interface of the electronic device such as a keyboard, touch-screen, keypad, etc. In an embodiment, the text input may be transmitted from another device. The text of the text input may be compared with a caption generated for a generated output later and similarity between the text of the natural language input and the caption for the generated caption may be calculated as a result of the comparison.

When a text of a natural language input is input to the NLU model 214, the NLU model 214 may analyze the text to obtain user intention information. The NLU model 214 may obtain action information, content information, content attribute information, and area information, etc., and the obtained information may be used to generate output content. User intention information may be obtained according to various categories in addition to the described information for the electronic device to understand intention of a user

FIG. 6A is a flowchart of a method of determining input content according to an embodiment of the disclosure.

FIG. 6B illustrates an example graphic user interface (GUI) for selection of input content according to an embodiment of the disclosure.

Referring to FIGS. 6A and 6B, an operation S330 of FIG. 3 may be performed differently based on whether a user input for selecting input content is received. The operation S330 may be performed after receiving a user input and a natural language input for selecting a target area 602 in base content 600, but is not limited thereto. For example, the input content may be determined before receiving a user input and a natural language input for selecting a target area 602 in base content 600.

In operation S331, whether a user input of selecting input content is received may be determined. When it is determined that a user input of selecting input content is received in operation S331, content selected by the user input may be determined as the input content in operation S332.

For example, referring to FIG. 6B, a GUI 603 for selecting input content may be displayed on a display of the electronic device, content may be selected from the GUI 603 by a user input as input content.

When it is determined that a user input of selecting input content is not received in operation S331, whether content information is included in user intention information may be determined in operation S333. When it is determined that content information is included in user intention information in operation S333, input content may be determined based on the content information in operation S334. For example, referring to FIG. 6B, when a natural language input saying “draw a cat perching on here” is received, “cat” may be identified as content information, and then the electronic device may determine a cat image as input content in response to identifying “cat” from text of the natural language input as the content information. In an embodiment, input content may be determined based on the content information under confirmation of a user. For example, a found content may be displayed based on the content information, and then the found content may be determined as input content when a user agrees to using the found content as the input content. When a plurality of pieces content are found based on the content information, a GUI 603 for selecting input content among the plurality of pieces of content may be displayed at the electronic device to allow a user to select input content.

When it is determined that content information is not included in user intention information in operation S333, a plurality of pieces of content may be displayed in operation S335. That is, a GUI 603 for selecting input content among the plurality of may be displayed at the electronic device, and then input content may be determined from the plurality of pieces of content based on a user input. The GUI 603 for determining input content may be displayed when content information is not obtained based on a natural language input as well as when content information is not included in user intention information.

FIG. 7A is a diagram for explaining a generative adversarial network (GAN) according to an embodiment of the disclosure.

The output content generating unit 240 may include an AI model for generating output content.

Referring to FIG. 7A, the output content generating unit 240 may include a generative model of the GAN model, that is, a generator 242. The output content generating unit 240 may further include a discriminative model of the GAN model, that is, a discriminator 244. The generator 242 and the discriminator 244 of the GAN model may be adversarially trained with each other. The discriminator 244 may be trained based on real content and fake content in order to determine whether output content generated by the generator 242 is a real or fake content. The generator 242 may generate, based on input data, output content which can be determined as real content by the discriminator 244. The generator 242 and the discriminator 244 may be trained until reaching a balance point. While the two networks reaches the balance point, a loss function of the GAN may be corrected appropriately to be enough to imitate data probability distribution of real content.

The generator 242 may generate output content based on input content and a target area of base content in operation S742. Output content generated by the generator 242 which has reached or approximated to the balance point may have probability distribution approximating to the probability distribution of the real content. The generator 242 may generate output content having probability distribution approximating to the probability distribution of the real content so that the output content is determined as real content by the discriminator 244.

The discriminator 244 may discriminate between a real and fake content with respect to a target area in operation S744. The discriminator 244 may discriminate between a real and fake content with respect to an entire area of base content in operation S745.

The generator 242 may be trained based on a result of discrimination of the discriminator 244 in operation S780. The discriminator 244 is trained to discriminate a real and fake content with respect to the target area and the entire area, and the generator 242 is trained to generate output content which can be determined as real content with respect to the target area and the entire area by the discriminator 244. Accordingly, the quality of the generated output content may be improved.

Referring to FIG. 4 , a probability that output content generated by the generator 242 is determined as real content by the discriminator 244 may approximate 0.5, but is not limited thereto. That is, data probability distribution of output content generated by the generator 242 may approximate to data probability distribution of real content. Real content which is used as references to discriminate may have the same form with base content or be supported by the same platform with base content. That is, real content which are collected in the same platform with base content or as having the same form with base content may be used to train the discriminator 244.

FIG. 7B is a diagram for explaining a method of using a caption according to an embodiment of the disclosure.

In an embodiment, the discriminator 244 may be further trained based on similarity between text of a natural language input and a caption for content. After the generator 242 and the discriminator 244 of GAN have reached a balance point, a probability that output content generated by the generator 242 in operation S742 is determined as fake content by the discriminator 244 may approximate to 0.5, but is not limited thereto.

Referring to FIG. 7B, the discriminator 244 may determine whether output content is a real or fake content based on similarity between text of a natural language input and a caption for output content. Particularly, a caption may be generated, by the caption generating unit, for output content which is generated by the generator 242, and similarity between the generated caption and the text of the natural language input of a user may be calculated by the similarity calculation unit. When it is determined that the similarity does not satisfy a predetermined condition in operation S746, the discriminator 244 may determine the generated output content as fake content. When it is determined that the similarity satisfy a predetermined condition in operation S746, the discriminator 244 may determine the generated output content as real content. In an embodiment, the discriminator 244 may be further trained based on the similarity between the text of the natural language input and the caption of the output content. Furthermore, the generator 242 is also trained in operation S780 to generate output content which can be determined as real content by the discriminator 244, the generator 242 may iterate a process of generating output content, which may improve the quality of the output content.

FIG. 8 is a diagram for explaining a method of changing an attribute of input content according to an embodiment of the disclosure.

Referring to FIG. 8 , a picture of parents may be selected as input content 804 by a user input 1. A target area 802 may be set in base content 800 based on a user input 2. When a natural language input saying “make them stand here” is received at the electronic device, the electronic device may obtain user intention information based on the natural language input. In the natural language input, “make” may correspond to action information In the natural language input, “them” may correspond to content information In the natural language input, “stand” modifying the content information may be identified as content attribute information indicating an attribute content.

In an embodiment, the output content 814 may be generated based on the content attribute information. The output content 814 may be generating by compositing the input content into the target area 802 of the base content 800. An attribute of the output content 814 may be identical to an attribute indicated by the content attribute information. An attribute of the output content 814 may be changed from an attribute of the input content 804. An attribute of content may include a pose, facial expression, make-up, hair, apparel, accessory, or style of content, but is not limited thereto. An attribute of content may include a pose, facial expression, make-up, hair, apparel, accessory, or style of an object in content, but is not limited thereto. For example, referring to FIG. 8 , an attribute of the input content 804, such as a pose, may be a sitting pose, and an attribute of the output content 814 may be a standing pose. A method of changing an attribute of the input content 804 will be explained later by referring to FIGS. 9 and 10 .

In an embodiment, the output content 814 may be generated to match with the base content 800. The output content 814 may be generated as having the same attribute with the base content 800 or an object in the base content 800 by referring to the target area 802 or entire area of the base content 800. For example, referring to FIG. 8 , when all objects in the base content 800 wear white clothes, the output content 814 in which objects also wear white clothes may be generated. That is, objects in the input content 804 are wearing clothes of different colors, but the output content 814 in which objects wear white clothes may be generated, and the base content 810 and/or its target area 812 may include the output content 814. For example, referring to FIG. 8 , when all objects in the base content 800 stand up, the output content 814 in which objects also stand up may be generated. That is, objects in the input content 804 are sitting on a floor, but the output content 814 in which objects stand up may be generated, and the base content 810 and/or its target area 812 may include the output content 814. A method of making the output content 814 to have the same attribute with the base content 810 will be explained by referring to FIGS. 9 and 10 .

FIG. 9 is a diagram for explaining a method of generating content by a GAN according to an embodiment of the disclosure.

In an embodiment, content attribute information may be obtained from a natural language expression modifying content information. The content attribute information may relate to an attribute that a user wants to change in input content. For example, when input content includes a person, an attribute among a pose, facial expression, make-up, hair, apparel, accessory, or style of the person that a user wants to change may be identified as content attribute information.

Referring to FIG. 9 , the output content generating unit may include two generators, that is, a first generator 242 a, and a second generator 242 b. Furthermore, the output content generating unit may include two discriminators, that is, a first discriminator 244 a, and a second discriminator 244 b.

The first generator 242 a may generate output content having “B” attribute based on input content having “A” attribute in operation S942 a. That is, the first generator 242 a may generate fake content having “B” attribute based on real content having “A” attribute. The first generator 242 a may be trained to generate output content having “B” attribute.

The second generator 242 b may reconstruct content having “A” attribute based on the generated output content having “B” attribute in operation S942 b. That is, the second generator 242 b may reconstruct an original content having “A” attribute from fake content having “B” attribute. The first generator 242 a may be trained to generate output content having “A” attribute. The first generator 242 a may only change an attribute of the input content, while changes to other attribute are suppressed, from “A” attribute to “B” attribute to generate the output content so that the second generator 242 b can reconstruct content similar to the original input content having “A” attribute. According to an embodiment, generation of content unrelated to the original content may be suppressed by reconstructing the original content. As a reconstructed content approximates to input content, a loss value may be reduced, which may be interpreted that cyclic consistency between the input content and the output content is maintained.

Meanwhile, whether the output content having “B” attribute generated by the first generator 242 a is a real or fake content may be discriminated by the first discriminator 244 a in operation S944 a. The first discriminator 244 a may be trained by using real content having “B” attribute to discriminate between a real and fake content. The first generator 242 a may be trained based on a result of discrimination of the first discriminator 244 a in operation S980 a.

Whether the content having “A” attribute reconstructed by the second generator 242 b is a real or fake content may be discriminated by the second discriminator 244 b in operation S944 b. The second discriminator 244 b may be trained by using real content having “A” attribute to discriminate between a real and fake content. The second generator 242 b may be trained based on a result of discrimination of the second discriminator 244 b in operation 980 b.

According to an embodiment, when an attribute of input content is changed from “A” attribute to “B” attribute, consistency of other attributes may be maintained. According to an embodiment, an attribute of input content may be changed from “A” attribute to “B” attribute without labelling on an attribute of content.

FIG. 10 is a diagram for explaining a method of generating content by a GAN according to an embodiment of the disclosure.

Referring to FIG. 10 , the output content generating unit may include a generator 242 and a discriminator 244.

The generator 242 may generate output content based on an attribute label and input content in operation S1042. The attribute label may indicate a label of any attribute which can be classified by the discriminator 244. That is, the generator 242 may receive an attribute label and input content to generate output content. The generator 242 may be trained to generate output content which can be determined by the discriminator 244 as real content and classified to the received attribute label.

The generator 242 may reconstruct content based on the same attribute label with one in operation S1042 and the output content in operation S1043. That is, the generator 242 may receive the initial attribute label and the generated output content to reconstruct content. The generator 242 may modify the input content only to the extent that the generated output content can be classified as the attribute label so that the generator 242 can reconstruct content close to the initial content (the input content). The input content is modified within the extent that the output content can be classified as the attribute label, the output content which is classified to the certain attribute may be generated. As the reconstructed content approximates to the input content, a loss value of the output content may be decreased.

Whether the output content generated by the generator 242 is a real or fake content may be discriminated by the discriminator 244 in operation S1044. When the output content is determined as real content, the discriminator 244 may classify an attribute of the output content in operation S1045. The discriminator 244 may receive real and fake content to discriminate a real or fake content. The discriminator 244 may classify an attribute of the output content, which is determined as real content, to train the discriminator 244.

The generator 242 may be trained based on a result of discrimination of the discriminator 244 in operation S1080.

According to an embodiment, when an attribute of input content is changed from “A” attribute to “B” attribute, consistency of other attributes may be maintained. FIG. 10 is explained with an example of changing only one attribute, but the number of attributes of input content that can be changed may increase according to the number of attributes that the discriminator 244 is configured to classify.

FIG. 11 is a diagram for explaining a method of using user feedback according to an embodiment of the disclosure.

Referring to FIG. 11 , the electronic device may receive user feedback on base content 1110 into which output content has been composited, output content, or an area of output content corresponding to a target area 1112 of input content. In an embodiment, when user feedback is received, a process of generating output content may be iterated. For example, similar to a case where similarity between a caption of output content and a natural language input does not satisfies a certain condition, a process of generating output content may be iterated when a negative user feedback is received.

According to an embodiment, the user feedback may be reflected on an AI model to provide a more customized result to a user.

FIG. 12 illustrates an example GUI for receiving a user's feedback according to an embodiment of the disclosure.

Referring to FIG. 12 , the electronic device may receive user feedback on base content 1210 into which output content has been composited, output content, or an area 1212 of output content corresponding to a target area 1212 of input content. In an embodiment, when user feedback is received, a GUI 1213 for changing an attribute of an object in input content may be displayed. For example, when a negative user feedback on an attribute of output content is received, the GUI for changing the attribute of the output content may be displayed so that a user may select his or her favorable attribute.

FIG. 13 is a diagram for explaining content generated in a workspace of an application according to an embodiment of the disclosure.

Referring to FIG. 13 , content of black cloud is determined as input content 1304, and a natural language input saying “put this cloud to fit in here” may be received at the electronic device. In an embodiment, when user inputs on target areas 1312 a, 1312 b, 1312 c and 1312 d are received, the electronic device may generate output content in the target area 1312 a, 1312 b, 1312 c, and 1312 d. The output content may be generated in relation with the base content by using an AI model. As shown in FIG. 13 , when a workspace 1310 includes another object, such as a white circle, the output content may be generated in relation with the workspace 1310 including the white circle object Relation between output content and the workspace 1310 may be obtained based on user intention information which is determined from a natural language input. For example, white clouds may be generated as a plurality of pieces of output content (work objects) by referring to the white cloud in the workspace 1310 based on expression of “to fit in here.” That is, output content which has a different color from the initial input content 1304 may be generated.

FIG. 14 is a diagram for explaining content generated adaptively to a workspace of an application according to an embodiment of the disclosure.

Referring to FIG. 14 , content of a silhouette of a woman holding a bag is determined as input content 1404, and a natural language input saying “make her hold an arrow like the left one” may be received at the electronic device. When a user input on a target area 1412 is received, the electronic device may generate output content in the target area 1412 by using an AI model.

Referring to FIG. 14 , when a workspace 1410 includes another object, such as silhouette of a man holding an arrow, the output content may be generated in relation with the workspace 1410 including the other object. For example, a silhouette of a woman holding an arrow like the man may be generated as output content by referring to the man holding an arrow in the workspace 1410 based on expression of “hold an arrow like the left one.”

FIG. 15 is a diagram for explaining a method of generating an animation of content according to an embodiment of the disclosure.

According to an embodiment, when base content is a workspace of an application, output content may be generated based on an API of the application. The API of the application may call for various commands related to an animation. The commands related to an animation may include commands for setting an action parameter of an animation (such as, appear, highlight, hide, move), a starting point and end point of the action parameter (such as where to appear, where to hide, where to move), a move direction of the action parameter, a move timing of the action parameter, a move speed of the action parameter, etc., but are not limited thereto.

Referring to FIG. 15 , output content may be an animation related to input content 1504. The input content 1504 may be a work object.

An animation related to the input content 1504 may be generated by using the above AI model, such as a GAN model. A generator of the GAN model may receive the input content 1504, the API of the application, and user intention information, and then combine commands provided by the API of the application to generate the animation related to the input content 1504, and the animation may animate according to intention of a user.

For example, when input content 1504 is selected in a workspace 1500, and a natural language input saying “apply an animation where this number is counted” is received at the electronic device, a generation of an animation may be identified as action information from “apply an animation.” An animation related to the input content 1504 may be generated in response to identifying the action information indicating the generating of the animation. The target area may be an area to which the input content 1504 is located in the workspace 1500, but is not limited thereto. An animation conforming to the intention of the user may be inferred from content attribute information. For example, “this number” may be identified as content information in the natural language input, and “is counted” modifying the content information may be identified as content attribute information. An animation may be generated based on the input content 1504, the API of the application, and the content attribute information of “is counted.”

The electronic device may generate a caption for the content 1514 to which the animation is applied. A caption for describing the animation of the content 1514 may be generated by using a video captioning model. A process of generating an animation may be iterated based on similarity between the generated caption and text of a natural language input. Accordingly, an animation conforming to user intention may be generated. According to an embodiment, an animation may be applied to the input content 1504 by using a natural language input, even though a user is not aware of exact commands of the application. An animation of the input content 1504 may function in a presentation mode of the workspace 1510.

FIG. 16 is a diagram for explaining an example animation generated according to an embodiment of the disclosure.

Referring to FIG. 16 , base content may be a workspace 1600 of an application, and input content 1604 may be a work object. For example, the work object may be created by a tool supported by the application.

When a work object is selected in a workspace 1600, and a natural language input saying “apply an animation where this graph grows laterally” is received at the electronic device, generation of an animation may be identified as action information from “apply an animation.” An animation related to the input content 1604 may be generated in response to identifying the action information indicating the generating of the animation. An animation conforming to the intention of the user may be inferred from content attribute information. For example, “this graph” may be identified as content information in the natural language input, and “grows laterally” modifying the content information may be identified as content attribute information. An animation may be generated based on the input content 1604, the API of the application, and the content attribute information of “grows laterally.”
